GitLab connects Cursor to development context via Model Context Protocol
GitLab's new MCP server brings project history and lifecycle data into Cursor, letting the AI coding agent access the same resources the user can reach.

GitLab has released a Model Context Protocol (MCP) server that brings software development lifecycle context into Cursor, an AI coding agent that can inspect code, explain failures, propose fixes, and run tests within a development workflow.
How GitLab context flows into Cursor
The GitLab MCP server is configured in Cursor by adding an HTTP-type MCP server definition with the GitLab instance URL in the mcp.json file. When Cursor authenticates with GitLab MCP, it acts with the user's existing GitLab identity and can only access projects and resources that the user can already access. GitLab Orbit, which provides a context graph across code, work items, merge requests, vulnerabilities and more, surfaces that information to Cursor for decision-making.
Workflow automation with GitLab Duo
Custom flows are generally available in GitLab 19.2, orchestrated through the GitLab Duo Agent Platform, which is designed to certify the work of coding agents. GitLab Duo Code Review Flow maintains style guides through instructions defined in the .gitlab/duo/mr-review-instructions.yaml file.
Java modernization as a use case
GitLab published a tutorial demonstrating three use cases: fixing a failing Java end-to-end test with Cursor, preparing quality gates for Java 8 to 21 modernization, and modernizing HTTP connection handling with Java 21. One example involves a Java HTTP metrics collector from the Tanuki IoT Platform that currently uses the legacy HttpURLConnection API from Java 8. The collector checks HTTP endpoints, records metrics such as response status and timing, and sends readings to its Rust metrics backend, which now fits into production architecture. Java 21 modernized the HTTP library with java.net.http.HttpClient as a replacement.
The java21-modernization agentic skill activates when a work item asks for Java 21 CI visibility, runtime or image upgrades, HttpClient migration, dependency or source API modernization, or review of maint-java-21 style merge requests.
